NON-PUNCTURABIE PNEUMATIC TIRE.

Specification of Letters Patent.

Patented Jan. 19, 1909.

Application filed January 18, 1908. Serial No. 411,546.

Toa ll whom it may concern:

Be it known that I, EDWIN A. STOREY, a

citizen of the United States, residing in the city and county ofPhiladelphia, State of Pennsylvania, have invented a new and usefulNon-Puncturable Pneumatic Tire, of which the following is aspecification.

My invention consists of a pneumatic tire provided with means forpreventing puncturing of the pneumatic tube thereof, the same embodyinga mail of non-puncturable material inclosed in the shoe of the tire andserving to guard said tube.

It also consists in formin the mail of articulated plates, thus renering the mail flexible or pliable so as to yield when'subjected to theload of the vehicle, thus obviating breaking or fracturing of the same.

It also consists of means for closing the joints of adjacent plateswithout affecting the articulation of the same.

For the purpose of explaining my invention, the aeompanying drawingillustrates a satisfactory reduction of the same to practice, but theimportant instrumentalities thereof may be varied.

Figure 1 represents a transverse section ofa pneumatic tire embodyingthe invention. Fig. 2 represents a section of a portion of the same ,inthe annular direction thereof. Fig. 3 represents-a plan view of the mailemployed.

Similar letters of reference indicate corresponding parts in thefigures.

Referring to'the drawings :A designates the shoe of the tire, the samebeing composed in part of a body A of soft rubber, and layers A ofrubber cloth, and having on its inner portion th'efshoulders B forattachment to the felly. Within the shoe is the tube C, which is adaptedto be inflatedfthe effect of which is communicated to the shoe so as toeffectively tighten the same.

D designates a mail, preferably of metal, which is inclosed in the shoeand extends in the circular direction of the same, so as to guard thetube G from puncture, the same being formed of a series of plates E,which are provided respectively with hooks F and cross bars F, theformer being adapted to engage the latter, whereby the 1plates areconnected one with the other and t eir joints Patent, is:

flexible in its nature and soproperly yields when the tread of thewheel. touches the road articulate, by which provision the mail is way,and thus as it is subjected to inward pressure it is prevented frombeing fractured and rendered useless. r

I11 order toprevent gaps between the ends of the plates which otherwisemight permit the passage therethrough of a nail or other object, thecross-bars F are set back from the edges of the plateand occupy slots Gin said edges, so that the hooks F engage said cross-bars some distancefrom said edges, by which provision the edge of one plate overlaps theedge of the adjacent plate, and thus the joint of the two plates iscovered without, however, affecting the articulation of the plates, theeffect of which is evident.

Upon reference to Fig. 3, it will be noted that the slot G is uponopposite sides of'the cross bar F. By this provision the hooks F whichare mounted on said'crossebars have their heads movable in theinner slotG, and the shanks of said hook movable on the outer slot G, said shankthus has a free play of said outer slot and causes the greatest freedomof articulation of adjacent plates E.

In order to guard the tube from frictional and consequently injuriousaction of the mail, the latter is interposed betweeii the layers A ofthe shoe, and thus covered by the latter, preventing direct contact ofsaid shoe with said tube.

Having thus described my invention, what I claim as new and desire tosecure by Letters 1.
